Anonymous got lucky. When five of its hackers attacked security company HBGary Federal on February 6, 2011, they were doing so in order to defend the group’s privacy. It wasn’t because they hoped to reveal plans to attack WikiLeaks, create surveillance cells targeting pro-union organizations, and sell sophisticated rootkits to the US government for use as offensive cyber weapons—but that’s what they found.
In the weeks after the attack, the hackers released tens of thousands of e-mail messages and made headlines around the world. Aaron Bar, the CEO of HBGary Federal, eventually resigned; 12 Congressman called for an investigation; an ethics complaint was lodged against a major DC law firm involved with some of the more dubious plans.

This book is designed to give readers of all backgrounds and experience levels a well-researched and engaging introduction to the fascinating realm of network security. With real-world examples that reflect today's most important and relevant security topics, Penetration Testing will address how and why people attack computers and networks, so that readers can be armed with the knowledge and techniques to successfully combat hackers. Because the world of information security changes so quickly and is often the subject of much hype, this book also aims to provide a clear differentiation between hacking myths and hacking facts. Straightforward in its approach, this valuable resource teaches the skills needed to go from hoping a system is secure to knowing that it is.
The SANS Institute maintains a list of the “Top 10 Software Vulnerabilities.” At the current time, over half of these vulnerabilities are exploitable by Buffer Overflow attacks, making this class of attack one of the most common and most dangerous weapon used by malicious attackers. This is the first book specifically aimed at detecting, exploiting, and preventing the most common and dangerous attacks.
Buffer overflows make up one of the largest collections of vulnerabilities in existence; And a large percentage of possible remote exploits are of the overflow variety. Almost all of the most devastating computer attacks to hit the Internet in recent years including SQL Slammer, Blaster, and I Love You attacks. If executed properly, an overflow vulnerability will allow an attacker to run arbitrary code on the victim's machine with the equivalent rights of whichever process was overflowed. This is often used to provide a remote shell onto the victim machine, which can be used for further exploitation.
A buffer overflow is an unexpected behavior that exists in certain programming languages. This book provides specific, real code examples on exploiting buffer overflow attacks from a hacker's perspective and defending against these attacks for the software developer.
*Over half of the “SANS TOP 10 Software Vulnerabilities” are related to buffer overflows.
*None of the current-best selling software security books focus exclusively on buffer overflows.

Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy programming. Many people call themselves hackers, but few have the strong technical foundation needed to really push the envelope.
Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundamentals of C programming from a hacker's perspective.
The included LiveCD provides a complete Linux programming and debugging environment–all without modifying your current operating system. Use it to follow along with the book's examples as you fill gaps in your knowledge and explore hacking techniques on your own. Get your hands dirty debugging code, overflowing buffers, hijacking network communications, bypassing protections, exploiting cryptographic weaknesses, and perhaps even inventing new exploits. This book will teach you how to:
Program computers using C, assembly language, and shell scripts
Corrupt system memory to run arbitrary code using buffer overflows and format strings
Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening
Outsmart common security measures like nonexecutable stacks and intrusion detection systems
Gain access to a remote server using port-binding or connect-back shellcode, and alter a server's logging behavior to hide your presence
Redirect network traffic, conceal open ports, and hijack TCP connections
Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrix
Hackers are always pushing the boundaries, investigating the unknown, and evolving their art. Even if you don't already know how to program, Hacking: The Art of Exploitation, 2nd Edition will give you a complete picture of programming, machine architecture, network communications, and existing hacking techniques. Combine this knowledge with the included Linux environment, and all you need is your own creativity.
“The threat to the Internet from worms, viruses, botnets, and zombie computers is real, and growing. Counting from Zero is a great way to come up to speed on the alarming state of affairs, and Johnston draws you in with his story and believable cast of characters.”
Today, every computer connected to the Internet is under constant attack from viruses, worms, port scans, and spam. Security professionals continually fight to contain newly unleashed cyber attacks, known as ‘zero day' attacks, only to have new attacks launched. Millions of computers have already succumbed, and, without their owner's knowledge, have become slave computers – remotely controlled ‘zombies'. Under the control of organized crime and backed by foreign governments, these computers are morphing into collections known in the industry as botnets, short for robot networks.
Internet security expert Mick O'Malley is the only one who recognizes the growing threat of the ultimate zero day attack on the Internet from a massive botnet, and his unique hacker skills and network of colleagues enable him to fight back. More cyber prep than cyber punk, Mick uses real-life tools and techniques to encrypt all his communications, and uses these skills to break the encryption used by the botnet. Mick uses encryption on a personal level, too, having multiple passports and multiple names and identities. While crisscrossing the globe in the air, on land, and at sea investigating the threat, Mick becomes the target of attacks on his reputation, his identity, and ultimately his life.
Along the way, Mick meets Kateryna Petrescu, a beautiful Romanian firewall expert. Mick's attraction to Kateryna develops as they work closely together and share the excitement and danger. Why is the government following Mick and trying to intercept his communications? Can he stop the zero day attack before it is unleashed? What will be the cost to Mick for his single mindedness?
Unfolding across three continents, the new cybercrime mystery “Counting from Zero” gives a realistic insider's view of the thrust and parry world of computer security and cryptography, and the very real threat of botnets.
